Hello
As I'm a beginner with the Simulink tool, I'm very interrested in example designs for System Generator. Can anyone post a link or something ?
I want to design filters which should run on a fpga (Xilinx Spartan 2 Xc2s200). But there are questions that the manual doesn't answer... (like : how do I access data from the fpga board sram to put it to the filter)

Hello Timo
When you install Sysgen there are many demos that are included in the install directory: %my_matlab_install%\toolbox\sysgen62\xilinx\sysgen\examples %my_matlab_install%\toolbox\sysgen62\xilinx\sysgen\examples\demos There are a number of different filters included in the examples.
If you are trying to read data from external sram (?) then you could use a memory controller to read data into the FPGA. If you are building a parallel filter then the data is usually applied directly to the filter after a couple pipeline stages for performance. If you are using a MAC structure then often you will want to use memory buffers to align your data with your coefficients.
